From: Shin'ichiro Kawasaki <shinichiro.kawas...@wdc.com>
Prevent scsi-hd and scsi-disk drivers from attaching a zoned block device
because it will appear as a regular block device at the guest and will
most certainly cause problems.
The functionality to support ZBDs is not planned for scsi-hd and
scsi-disk legacy drivers. It is supported via scsi-generic driver already
and discussion is ongoing for scsi-block driver.
